In the previous paper Storage Spaces Performance in Windows Server 2012 Essentials on a HP N40L ProLiant MicroServer I ran performance tests on a number of Virtual Disks in Storage Spaces in Windows Server 2012 Essentials with a Storage Spaces Pool made up of Seagate ST3000DM001’s. While I speculated that recent testing I had done in Creating and Measuring the Performance of a Storage Space Pool in Windows Server 2012 Essentials R2 Preview on a HP ProLiant N40L MicroServer would be relevant when I was able to free up four Seagate ST3000DM001’s — I took this opportunity to test Virtual Disk performance in Storage Spaces for a pool made up of Three and then Four physical ST3000DM001’s.

I first began my testing with three Seagate ST3000DM001’s in my Storage Space Pool:

Figure 2 shows the Physical and Logical view of how Storage Spaces works and how we will set it up in the beginning of the video.

Figure 9 shows the Physical and Logical view of how Storage Spaces works and how it will be set up after I add a fourth Seagate ST3000DM001 to the Pool.

While adding a physical drive to the Pool does increase the available Pool size supporting the virtual disks in Storage Spaces it did not seem to do anything to improve the performance of any of the three virtual dives being tested.

    Thanks for your Review!
    Am I right saing:
    The Storage Space Writing performance on parity space on Win 2012 was very bad and is still very bad on R2?"
